The Emtek EMPowered Touchscreen Keypad Deadbolt is a touchscreen keypad lock with a motorized deadbolt which offers key-less entry meaning that there are no keys to lose or cylinders to bump or pick. Operation of the deadbolt is by code entry from the outside and by thumb-turn from the inside. When leaving, a simple touch on the keypad locks the deadbolt. Furthermore, one can set the lock to automatically re-lock itself after a certain period thereby ensuring that the door is lock at all times. Up to 25 user codes can be stored and created meaning the duplication of multiple physical keys is eliminated. The keypad itself is backlit allowing for easy use in the dark and the lock features a metal housing protecting internal components from harsh weather conditions. It has a silent motorized deadbolt which is powered by 4 AA batteries and there is a backup power supply to prevent lockout. It has a tapered deadbolt which accommodates it for use on misaligned doors. Installation is simple as it is designed to easily fit on standard door and only requires a screwdriver when fitting. The lock will guide you through set up and menu options in 3 languages.
